Abstract
Using a simple electrochemical deposition (ECD) method, β-nickel hydroxide (β-Ni(OH)2) nanosheets (NSs) are facilely integrated on non-woven conductive textile substrate (NWCTs). The NWCTs with copper-plated polyethylenterephthalate (Cu/PET) fibers serves as a highly conductive and low-cost working substrate for the ECD method. With an aid of direct current voltage in the growth solution, the β-Ni(OH)2 NSs well adhere to NWCTs fibers with good uniformity. The surface morphology and crystallinity properties of the synthesized β-Ni(OH)2 NSs on NWCTs are characterized by various physicochemical techniques. Furthermore, the hierarchical β-Ni(OH)2 NSs on NWCTs reveal superior energy storage performance in 1 M KOH electrolyte solution as a binder-free electrode for pseudocapacitors. Compared to the conventional conductive foil-based electrode, the pseudocapacitive electrode in this work exhibit a relatively high electrochemical performance (specific capacitance of 2185.6 F g–1 at 5 A g–1) and stable capacitance...
